Implantable Collamer Lens or Visian ICL Risks and Complications

  • 3 min read

Visian ICL is probably the most advanced technology present in the market today for vision correction. However, as with any other medical procedure, its benefits do not come without risks. There are a few possible Visian ICL problems that patients may encounter as well as have to be aware of:

Overcorrection and Undercorrection

Although a skilled surgeon makes use of the 3D advanced technology to make measurements before surgery, the measurements are not always perfect. Therefore overcorrection and undercorrection can occur. Similar to other refractive procedures, undercorrection in Visian ICL can be fixed with an additional procedure or with continued use of prescriptive eyewear. Toric Visian ICL for Vision Correction – Westlake Village Beverly Hills Lasik Cataract Surgery


Infection is not a very common risk or problem but since the procedure involves a small form of manipulation there still is a slight risk of eye infection, which could in turn delay the healing process.

Night Glare and Halos

Halos and night glare are the most common side effect of any refractive surgery. Visian ICL patients may still experience night glare and halos but the cases are less compared to those who have Lasik.

Damage to Crystalline Lens

Because Visian ICL is positioned inside of the eye, there is a potential risk of it touching the natural lenses. This could result to less opacity of the lens and in extreme cases it may lead to the need to replace the natural lens with synthetic ones.

Iridotomy Complications

The process of iridotomy or making a small opening near the edges of the iris using a laser is done during Visian ICL. Although complications from iridotomy are very rare, it could also lead to inflammation, corneal damage, scar formation, and intraocularpressure increase.

Pressure problems

Sometimes the new lens inserted in the eye prevents the movement of fluid. This leads to an increase accumulation of the eye fluid behind the colored part of the eye. This can be painful and the surgeon must be immediately informed. The pressure needs to be brought down medically or surgically.


There may be a mismatch between the size of the lens and the space in the eye. This causes the lens to move forward and called anterior vaulting. This may also result in increase intraocular pressure as mentioned above.

So far, according to the company out of the 300,000 eyes with Visian ICL, there has been less than 1% of issue post procedure. The problems and risks associated with Visian ICL should be thoroughly discussed by our doctors before the procedure is agreed upon and performed on a patient.

Visian ICL is a great option for people with high powers or people who cannot wear soft lenses. We hope this information on Risks and Problems Associated with Visian ICL will prove helpful in your research.
